调速阀:在载荷压力变化时能保持节流阀的进出口压差为定值。这样,在节流口面积调定以后,不论载荷压力如何变化,调速阀都能保持通过节流阀的流量不变,从而使执行元件的运动速度稳定。DSHG-03-2B2-D24-N1-14DSHG-03-2B2-D24-N-14

(3)分流阀:不论载荷大小,能使同一油源的两个执行元件得到相等流量的为等量分流阀或同步阀;得到按比例分配流量的为比例分流阀。
(4)集流阀:作用与分流阀相反,使流入集流阀的流量按比例分配。
(5)分流集流阀:兼具分流阀和集流阀两种功能DSHG-06-2B3B-D24-N1-53 DSHG-06-3C4-A100-53

效率不是一个独立性能参数,它可以由别的性能参数例如流
量、扬程和轴功率按公式计算求得。反之,已知流量、扬程
和效率,也可求出轴功率。
泵的各个性能参数之间存在着一定的相互依赖变化关系,可
以通过对泵进行试验,分别测得和算出参数值,并画成曲线
来表示,这些曲线称为泵的特性曲线。每一台泵都有特定的
特性曲线,由泵制造厂提供。通常在工厂给出的特性曲线上
还标明推荐使用的性能区段,称为该泵的工作范围。DSHG-04-2B10B-A120-52
